Unless you specify it manually (by using the Weight configuration
option), tinc will use the time it takes to make a connection to a peer
as the weight. So peers with a higher latency, lower bandwidth and/or
lower CPU power will get a higher weight.

Weight is used for creating a minimum spanning tree for forwarding
broadcast packets. With tinc 1.1, weight is also used to decide which
node to forward packets to if direct communication with the destination
node is not possible, if there is a tie between multiple paths with the
same minimum number of hops.

d here means that PMTU discovery and MSS clamping is enabled.
